BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a working table, and more particularly to a working table including a vacuum cleaner or vacuum mechanism for easily drawing and collecting the cut off dusts or contaminants and for allowing the collected dusts or contaminants to be easily removed or discarded.

2. Description of the Prior Art

Typical working tables, working machines, or table tools or table saws comprise a planar platform for supporting the work pieces, and a working tool for cutting or grinding or machining the work pieces.

For example, U.S. Pat. No. 5,301,579 to Shiotani et al., and U.S. Pat. No. 6,532,643 to Wang disclose two of the typical table tools or scroll saw machines each also comprising a platform for supporting the work pieces, and a working tool for cutting or grinding or machining the work pieces, and a lot of cut off dusts or contaminants may be generated when the working tool is working on the work pieces.

For covering the working tool and for preventing the cut off dusts or contaminants from flying everywhere, a safety cover or safety shield is required to be provided and attached onto or engaged with the working tool for suitably covering the working tool.

However, no vacuum cleaners or vacuum mechanisms are provided for drawing and collecting the cut off dusts or contaminants such that the cut off dusts or contaminants may also fly everywhere.

U.S. Pat. No. 5,722,472 to Wang, and U.S. Pat. No. 5,967,717 to Tucker et al. disclose two further typical table tools or working machines each also comprising a platform for supporting the work pieces, and a working tool for cutting or grinding or machining the work pieces, and a tubular extension is directed toward the working tool for suitably drawing and collecting the cut off dusts or contaminants.

However, the tubular extension is directed toward only one side of the working tool and may not suitably draw and collect the cut off dusts or contaminants.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional working tables or working machines.
